This section briefly introduces the methodology employed for this Report, which focuses on employees. It is assumed that their annual income from employment is equal to a given fraction of the average gross wage earnings of adult, full-time workers covering industry Sectors C-K inclusive with reference to the International Standard Industrial Classification of All Economic Activities, Revision 3 (ISIC Rev. 3)* of each OECD economy, also referred to as the average wage. Further details are provided in Part IV of this Report. Additional assumptions are made regarding other relevant personal circumstances of these wage earners in order to determine their tax/benefit position. The taxes included in the present Report are confined to personal income tax, social security contributions and payroll taxes (which, in this Report, are aggregated with employer social contributions in the calculation of tax rates), payable on gross wage earnings. Consequently, any income tax that might be due on non-wage income, as well as all other kinds of taxes – e.g. corporate income tax, net wealth tax and consumption taxes – are not taken into account in this Report. The benefits included are those paid by general government as cash transfers, usually in respect of dependent children.

Binding wage floors can have a significant impact on the wage distribution and the costs faced by employers. International comparisons of minimum-wage levels have largely focused on the gross value of minimum wages, ignoring the effects of taxation on both labour costs and the net income of employees. This paper presents estimates of the tax burdens facing minimum-wage workers. These are used as a basis for cross-country comparisons of the net earnings of these workers as well as the cost of employing them. In addition, results show the evolution of net incomes and labour costs during the past six years and the relative importance of minimum-wage adjustments and tax reforms in driving these changes.

This Part provides unique information for each of the OECD countries on the income taxes paid by workers, their social security contributions, the family benefits they receive in the form of cash transfers as well as the social security contributions and payroll taxes paid by their employers. Results reported include the marginal and average tax burden for eight different family types. These data are widely used in academic research and in the formulation and evaluation of social and economic policies. The taxpayer specific detail in this Report enables it to complement the information provided annually in the Revenue Statistics, a publication providing internationally comparative data on tax levels and tax structures in its the thirty member countries. This Part provides detailed results for 2006, definitive results for 2005 and discusses the changes between 2005 and 2006.

The personal circumstances of taxpayers vary greatly. To identify representative taxpayers and to calculate the amount of their taxes, this Report uses a specific methodology. The focus is on employees. It is assumed that their annual income from employment is equal to a given fraction of the average gross wage earnings of adult, fulltime workers in a broad range of industry sectors of each OECD economy. Additional assumptions are made regarding other relevant personal circumstances of these wage earners to enable their tax/benefit position to be determined. Table IV.1 sets out the terminology used in this Report, while Table IV.2 provides information on the industry sectors covered.
